Fran Kirby says England will show their tactical flexibility against Mexico on Saturday.
Mark Sampson’s side began their World Cup campaign with a 1-0 defeat by France after setting up in a cautious 4-1-4-1 formation.
But, with the Lionesses needing to pick up points at the weekend, Kirby believes they will be more adventurous in their second Group F match.

The 21-year-old said: “There has not been anyone who has been downhearted and there’s nobody that doesn’t think that we can’t prove a point against Mexico.
“There are 23 players in this squad and the [same] 11 won’t start every game. Mark is going to change it up a bit, he’s going to play certain ways to suit different opponents.
“We’re looking forward to attacking against Mexico and hopefully play some really nice football and get the win.”
Kirby continued: “Mark would have known for a long time what system he wants to play against Mexico. [The coaches] have been doing loads of work on all three [Group F opponents] ever since we were drawn against them.
“They have looked at what Mexico are good at, what Colombia are good at, what they are not so good at, what their weaknesses are, and they pick players to suit that game.”
Fran Kirby speaks to FATV
Kirby came on as a substitute against France to make her World Cup debut on her 10th international appearance.
The Reading star is one of six forwards in the England squad and she is determined to stake her claim for a place in the starting 11.
She added: “It would mean everything to me. Getting on the other day was amazing. I’m fit and ready to go.
“[Making] my World Cup debut has spurred me on that little bit more.
“I’m going to get out on the training pitch to try and really cement my place and give [Sampson] more of a headache than he’s already got.”
Following the Mexico game, England’s final group match is against Colombia in Montreal on 17 June.
